Going the extra mile(s) can help you run more efficiently at every distance—even if you dread it sometimes.

Ah, long runs: We love to hate ‘em. Or maybe we love to love ‘em—depends on who you ask. Either way, the long run is the cornerstone of any half marathon or marathon training plan, but it can be equally important to your 5K and 10K training. No races on your calendar? No problem. A long run can still be beneficial for your overall fitness and mental health.

But if you don’t understand the long run, you may miss out on all of the magic it has to offer. So we put together this ultimate guide to one of the best training tools you have in your arsenal.

What’s the point of the long run?

The benefit of running long—regardless of the distance you’re training for—is the aerobic gain you’ll make during those miles. “Long runs force the body to become more and more efficient,” says Ben Rosario, head coach and founder of the HOKA NAZ Elite team in Flagstaff, AZ. “The heart learns to pump higher amounts of blood with each stroke, which then carries more oxygen to the body.”

Aerobic (or endurance) running also strengthens your slow-twitch muscle fibers, which can fire repeatedly with minimal fatigue (compared to fast-twitch fibers, which are used during short, explosive efforts but fatigue more quickly). These fibers are also important because they’re full of capillaries, mitochondria, and myoglobin (an iron- and oxygen-binding protein), all of which are crucial to getting a steady supply of oxygen and energy to the muscles.

“Long runs force the body to create new capillaries, giving the oxygen a smoother and faster path to the mitochondria—a.k.a. the ‘power plant’ of the cells—where energy is produced and stored. And when we run for long periods of time, the size of those mitochondria increases, allowing them to produce and store more energy,” explains Rosario.

One of the other major benefits of the long run is how it teaches your body to use fat as fuel over carbs, says Joe McConkey, a Boston-based exercise physiologist and USATF-certified running coach. “That allows you to be more efficient with your different forms of energy, so you can run faster without depleting your reserves.”

Translation: The long run prepares your body to run more efficiently no matter the distance—even in a short race, when you need energy to be produced and oxygen sent throughout the body fast.

And you can’t overlook the mental angle: To prepare for the psychological challenge of racing for hours, you have to train for hours. Even if you’re not racing, a long run offers your mind the chance to tap into the ever-elusive runner’s high, and research shows running can boost your mood and improve your mental health.

What to Watch Out for On a Long Run

A long run is, inherently, long. And the more time you spend on your feet, the more stress you put on your body. “The long run does ask a lot of our muscles, tendons, and ligaments due to the duration of exercise required for a run to be considered ‘long’,” says Rosario. 
​

Generally, your cardiovascular system adapts to changes more quickly than your musculoskeletal system. So if you start running long before your body is prepared to run long, you could put yourself at an increased risk for injury, including overuse injuries like plantar fasciitis, Achilles tendonitis, runners’ knee, iliotibial band (ITB) syndrome, and shin splints.

“If you’re experiencing any little niggles or asymmetries before the long run, the long run will only make those worse with the thousands and thousands of steps you’re putting on your body,” says McConkey. It’s super important to listen to your body and, if you feel like something is off during the long run, acknowledge that it may be more major than you think. “The only sensations you should feel during a long run are a slight challenge aerobically as it gets longer, and general fatigue or a sort of bilateral soreness,” he adds.

Gear You Need for a Long Run

Running is a pretty simple sport in terms of gear, but when you start clocking over 60 minutes, there are some important things you’ll want with you beyond a good pair of shoes.

The most important addition is a way to carry fuel and hydration, whether that’s a running belt, a handheld water carrier, or a pack.

How Long Should Your Long Run Be?

There’s a huge amount of variation in how long a long run should be, depending on the type of runner you are.

Some coaches suggest long runs cover one-and-a-half to two times the distance of what you consider a normal-length run. Most experts, like Jack Daniels, agree that a long run be about 20 to 25 percent of your overall weekly mileage. So if you’re running 40 miles per week, your long run will be 8 to 10 miles.

“I typically don’t like the long run to be more than twice the length of a regular recovery run,” says McConkey (in general, recovery runs last about 25 to 40 minutes). According to the Road Runners Club of America, a long run technically isn’t a “long run” unless it’s over 90 minutes, so the exact distance depends on your running pace.

But your long-run distance becomes more specific if you’re training for a certain distance. Remember: You need to go further (and slower) in order to run faster at shorter distances. Most experts recommend working up to the below peak long run for each distance:

5K: 5 to 6 miles for beginners; 10 to 12 miles for intermediate/advanced

8K/10K: 6 to 10 miles for beginners; 12 to 14 for intermediate/advanced

Half marathon: 12 to 13 for beginners; 16 to 18 for intermediate/advanced

Marathon: 18 to 22 for beginners; 18 to 30 for intermediate/advanced

Yes, some of those distances are longer than the race itself. “But logging those miles shows you’ve spent enough time at sub-max speeds to allow the necessary aerobic adaptations to happen,” he explains.

How Fast Should Your Long Run Be?

No matter the distance, your long run should be run at an easy pace, says McConkey. We will repeat: easy pace! What does that translate to? It’ll be different for every runner, but an easy pace should fall on the lower end of the rate of perceived exertion scale. Your heart rate should be 50 to 70 percent of your maximum heart rate, and you should be breathing naturally and able to hold a conversation effortlessly.

"I advise people to run as slow as possible, as long as it’s mechanically comfortable,” McConkey explains. “I challenge people to not look at pace until they’re done, but just focus on something comfortable. You shouldn’t feel like you’re doing slow-motion single-leg squats; there should still be some spring to your step.”

That pace is going to change as your fitness changes. “When you develop more strength and running efficiency, you’ll be able to run faster at the same RPE or heart rate,” says McConkey.

For shorter distances, long runs can generally be slow and enjoyable, says Rosario. But half marathoners and marathoners should approach their long runs with a little more structure. “Half marathoners and marathoners, in my opinion, should be adding faster-paced running into most of their long runs: things like alternating fast-pace and medium-pace miles, surging for two minutes at the beginning of each mile, or simply running the last 5K of their long run really fast,” says Rosario. This is important, because it helps train your legs to get used to running fast even with lots of miles on them—and that will help at the end of races.

How to Recover From a Long Run

You may run your long run at an easier pace, but the sheer amount of time you’re spending on your feet warrants more rest and recovery.

For starters, “the quicker an athlete can replenish after a long run, the sooner they will recover,” says Rosario. “Shoot for a mix of carbs and protein, preferably at a 4:1 carbs to protein ratio—that particular ratio has been shown in labs to be the most effective at replenishing muscle glycogen stores and thus limiting muscle damage.”

McConkey recommends taking the day off after a long run. “Instead of running, just walk around for 20 to 30 minutes and spend 10 minutes on a foam roller to open up your body,” he says. “Those two things can really expedite recovery.” In fact, foam rolling was shown to reduce delayed-onset muscle soreness while enhancing muscle recovery in a study published in the Journal of Athletic Training. 


As for other trendy recovery modalities, do what feels good to you. Compression boots can also lead to recovery benefits, a study in the Journal of Applied Physiology found. Ice baths were shown to reduce delayed onset muscle soreness in a scientific review by researchers at the Cochrane Library. And massage helped reduce pain intensity in runners’ quads in a study from the Journal of Physiotherapy.

Most importantly, prioritize a good night’s sleep—new research from the International Journal of Sports Medicine argues it may be the single most important factor in exercise recovery. After all, that’s where the real recovery magic happens, when your body truly has time to rest and rebuild.

Three extraordinary performances that captivated the athletics world have now been officially ratified by World Athletics, with Jacob Kiplimo, Ja’Kobe Tharp and Emmanuel Wanyonyi securing their places in the history books with remarkable world-record performances.

Uganda’s Jacob Kiplimo delivered a breathtaking 57:20 at the EDP Lisbon Half Marathon on 8 March 2026, producing what was then a spectacular world record. His performance underlined his exceptional ability over the half-marathon distance and further strengthened his status as one of the finest road runners of his generation.

American hurdler Ja’Kobe Tharp created his own piece of history in Eugene on 10 June 2026, storming to 12.75 seconds in the 110m hurdles. The sensational performance came with a legal +1.0m/s following wind and established Tharp as the new world record-holder, marking a remarkable breakthrough on the global stage.

Kenya’s Emmanuel Wanyonyi completed the trio with a sensational 2:11.83 world record in the 1000m. The Olympic champion produced the performance in Monaco, lowering Noah Ngeny’s long-standing 2:11.96 world record from 1999. It was another extraordinary demonstration of Wanyonyi’s speed, strength and versatility beyond his specialist 800m distance.

What makes the three records particularly special is the variety of disciplines involved. Kiplimo conquered the demanding half marathon, Tharp mastered the technical challenge of sprint hurdling, while Wanyonyi extended his middle-distance brilliance over 1000m. Each performance showcased a different form of athletic excellence, yet all three athletes reached the same extraordinary destination: the world-record books.

Accuracy Note: Kiplimo’s 57:20 has since been surpassed by Ethiopia’s Yomif Kejelcha, who ran 56:51 at the Media Maratón Ciudad de Buenos Aires on 23 August 2026, taking 29 seconds off Kiplimo’s mark. The newer performance was still listed as pending ratification, meaning Kiplimo’s mark had been overtaken on the clock even as his record was among those formally ratified.

The ratification of the Kiplimo, Tharp and Wanyonyi performances nevertheless gives official recognition to three spectacular moments that will remain significant chapters in the 2026 athletics season.

Three athletes. Three extraordinary performances. Three officially ratified world records. From Lisbon to Eugene and Monaco, Kiplimo, Tharp and Wanyonyi have added another unforgettable chapter to the story of athletics

Uganda’s rapidly rising distance-running star Harbert Kibet has been provisionally suspended by the Athletics Integrity Unit (AIU) over the alleged presence and use of prohibited substances.

The 21-year-old is facing allegations involving triamcinolone acetonide and exogenous steroids, with the substances reportedly confirmed through Isotope Ratio Mass Spectrometry (IRMS) analysis. The development brings an abrupt halt to what had appeared to be the emergence of one of Uganda’s most promising young distance-running talents.

Kibet had enjoyed a remarkable breakthrough in February when he made his road 10-kilometre debut at the 10K Facsa Castellón in Spain. He produced a stunning performance to win in a world-leading 26:39, a time that placed him at No. 4 on the all-time road 10K list at the time and immediately elevated his status in international distance running.

His rapid rise had already earned him opportunities to represent Uganda on the global stage. Kibet competed for his country at the World Championships in Tokyo last year, although he did not progress beyond the heats.

His most recent competition came in May at the Xiamen Diamond League, where he finished 15th in the men's 5000 metres in 13:46.45. He has not competed since that race.

The provisional suspension now casts uncertainty over the immediate future of an athlete whose spectacular 10K performance earlier this year had generated enormous excitement. However, it is important to stress that a provisional suspension is not a final finding of an anti-doping rule violation.

The case will now continue through the appropriate anti-doping process, during which the evidence and circumstances surrounding the allegations will be considered before any final decision is reached.

For Kibet, the development represents a dramatic and unexpected turn in a season that had begun with one of the most remarkable performances in the history of road distance running. The athletics world will now await further developments as the AIU process moves forward.

The women’s 100m hurdles is set for a spectacular showdown at the Brussels Diamond League Final on September 5, where Olympic champion Masai Russell will lead one of the strongest fields of the season in the battle for the coveted Diamond Trophy.

Russell arrives in Brussels in extraordinary form and as the athlete everyone will be chasing. The American star has enjoyed a remarkable season, combining consistency with breathtaking speed, and recently delivered another unforgettable performance when she ran a sensational 12.09 seconds in Zurich to break the world record.

That performance further strengthened Russell’s position as the dominant force in the event. Her remarkable consistency has been equally impressive, with the Olympic champion winning all 10 of her finals so far this season. With 48 points, she also finished at the top of the Diamond League standings during the regular season.

However, the points race is now behind her. In Brussels, everything comes down to one final. The Diamond League Final offers no room for complacency, and Russell will have to defeat an exceptional collection of world-class hurdlers to leave Belgium with the Diamond Trophy.

Among her biggest challengers is Nigeria’s Tobi Amusan, one of the finest hurdlers of her generation and a former world record holder. The field also includes Dutch star Nadine Visser, Bahamas standout Devynne Charlton and Poland’s Pia Skrzyszowska, ensuring that Russell will face serious opposition over every hurdle.

American Alaysha Johnson, Jamaica’s Megan Simmonds and Belgium’s Yanla Ndjip-Nyemeck complete a fascinating eight-athlete lineup for what promises to be one of the highlights of the Diamond League Final.

With Russell’s unbeaten record, her recent world-record performance and the Diamond Trophy on the line, the pressure will be immense when the athletes take their marks. Yet in an event as unpredictable and technically demanding as the 100m hurdles, one mistake can completely change the outcome.

Russell may arrive as the overwhelming favourite, but Brussels offers her rivals one final opportunity to produce something special. The stage is set for a thrilling race between the fastest and most accomplished hurdlers in the world—and after a season of dominance, Russell now has one more hurdle to clear in her pursuit of Diamond League glory.

Women’s 100m Hurdles Final Start List

 1. Masai Russell — United States

 2. Tobi Amusan — Nigeria

 3. Nadine Visser — Netherlands

 4. Devynne Charlton — Bahamas

 5. Pia Skrzyszowska — Poland

 6. Alaysha Johnson — United States

 7. Megan Simmonds — Jamaica

 8. Yanla Ndjip-Nyemeck — Belgium

One race. Eight elite hurdlers. One Diamond Trophy. Will Masai Russell complete another unforgettable chapter of her remarkable season, or will Brussels produce a surprise?

The 2026 Bank of America Chicago Marathon is set to introduce an important new innovation that could change the way runners approach hydration during major road races.

For the first time, participants in an Abbott World Marathon Major will have the opportunity to refill their own approved, self-carried hydration containers while competing on the course. The initiative will make its debut through four Culligan Water Refill Stations strategically positioned along the 26.2-mile route.

The refill stations will be located shortly before Aid Station 4 at Mile 5.7, Aid Station 7 at Mile 10.1, Aid Station 12 at Mile 15.7 and Aid Station 16 at Mile 20.3. At each location, runners carrying approved personal hydration gear will be able to stop and refill with Culligan-filtered water before continuing their race.

The move represents a significant step forward for one of the world's most prestigious marathons. Chicago will become the first Abbott World Marathon Major to formally provide runners with the opportunity to refill personal hydration containers during the race, opening the door to a potentially more sustainable approach to supporting thousands of participants over the marathon distance.

Beyond the environmental benefits, the initiative will also be fascinating to watch from a sporting perspective. Hydration is a crucial part of marathon performance, particularly for runners competing over more than two hours and for the many recreational athletes spending considerably longer on the course. The effectiveness and convenience of the refill stations, as well as how smoothly runners are able to use them without disrupting their rhythm, will be closely observed.

The project is also designed to reduce reliance on single-use hydration products while giving runners greater flexibility and control over how they manage their fluids during the race. If successfully implemented, Chicago's new approach could provide an important example for other major endurance events around the world.

Culligan International President and Chief Operating Officer Al Hamood said the company's involvement reflects its wider commitment to innovation, sustainability and improving the race-day experience for athletes.

The 2026 Chicago Marathon will therefore offer much more than another spectacular day of elite racing and personal achievement. It will also serve as a live test of an idea that could help shape the future of hydration at major marathons.

When the 2026 Bank of America Chicago Marathon gets underway, runners will not only be racing against the clock—they will also be part of something entirely new. At four points along the legendary 26.2-mile course, a simple refill could become a glimpse into the future of marathon running. The real question will be how smoothly thousands of athletes embrace the system and whether Chicago's bold experiment can set a new standard for the sport. If it succeeds, the ripple effect could extend far beyond the streets of Chicago, inspiring major races around the world to rethink how they keep runners hydrated while reducing waste. In 2026, one of marathon running's biggest stages will be testing a small but potentially game-changing idea—proving that sometimes the future of the sport may be waiting at the next water refill station.

Indianapolis is set to become the home of American indoor track and field for the next two years after USA Track & Field confirmed that the city will host the 2027 and 2028 USATF Indoor Championships at the Indiana State Fairgrounds.

The nation’s leading athletes will compete at the Indiana Farm Bureau Fall Creek Pavilion, with the 2027 championships scheduled for February 19–21, followed by the 2028 edition from February 18–20.

The announcement marks a significant moment for Indianapolis and its long-standing connection with the sport. The 2027 championships will take place 40 years after the city hosted the inaugural World Indoor Championships at the Hoosier Dome in 1987, bringing another major chapter of elite indoor athletics back to a city with a rich track and field history.

Although Indianapolis is home to USA Track & Field's national office and has hosted major athletics competitions over the years, the upcoming editions will be the first time the city has staged the USATF Indoor Championships. The Indiana State Fairgrounds has nevertheless developed into an increasingly important venue for the sport, providing a major platform for elite indoor competition.

The consecutive championships will give athletes two years of high-stakes competition on one of America's growing indoor stages, with national titles and places among the country's finest athletes once again on the line.

The 2028 USATF Indoor Championships will carry even greater significance, serving as a selection event for athletes hoping to represent the United States at the 2028 World Athletics Indoor Championships in Odisha, India. That will add another layer of intensity to the competition as athletes battle not only for national honours but also for the opportunity to compete on the global stage.

For Indianapolis, the return represents more than simply hosting another national championship. Four decades after welcoming the world's finest athletes for the inaugural World Indoor Championships, the city is preparing to once again place track and field firmly in the national spotlight.

With two consecutive editions now secured, Indianapolis is ready to welcome America's best indoor athletes as they chase national glory, international selection and the chance to create another memorable chapter in the city's proud athletics history.
